Hi,
I send my sketch of the Moon. The sketch was made on Aug. 25, 2012, by means of white watercolor and dry pastel. That night the moon was 8 days after the new moon. He was low on the horizon but still was strong in my telescope. This is my first picture of the moon.

Located on the northern border of Mare Humorum, crater Gassendi is an impact crater formed during the Nectarian period (-3.92 to 3.85 billion years ago) that later was modified after volcanic activity, becoming a fractured-floor crater. Gassendi is believed to have been filled with lava from the inside, raising its floor, creating stress fractures in the process. This would explain it being considered a walled plain with a shallow depth of 2.8 km. The central peaks (~1200 m high) remain and several rilles (called Rimae Gassendi) were formed on the lava-filled floor during the Imbrian geological period -3.85 to –3.2 billion years ago.
Crater Gassendi A was formed during the Copernician period (–1.1 billion years ago to the present day) and overlaps Gassendi’s northern rim. The pairing of Gassendi and Gassendi A resembles a diamond ring and makes a very striking feature to observe 3 days after first quarter or two days after last quarter of lunation. My observation was nearly three days after first quarter.
Gassendi’s southern rim was swallowed by the lava of Mare Humorum leaving only a thin crest line to support its circular shape. Dorsa ran from the southern rim to Gassendi O (11 km wide). The sharp ridge that defines the border of Mare Humorum to the SW of Gassendi adds to the crater’s unmistakable identification.
At the beginning of my session, Spica and Saturn lined up to align with the Moon. Spica was 2.08 degrees north of the Moon and Saturn was 6.9 degrees north of the Moon. Extending further north, Arcturus was nearly in line as well at 31.8 degrees north of the Moon
Hello!
I present to you my latest sketch of the Jupiter.
Sketch was made by pastels on the navy blue paper and it is also some corrected with GIMP (especially the roundness of the planet).
Jupiter was observed through my SCT 5″ on December 1st, 2012.
Best regards!

I have observed rima Petavius several times .
One exellant seeing night, 2011. 9[september] .14 …. , I ,d found out with my 8″ refractor at x 340 the three tuna-fish like convex hills on the middle of the 80 km long rima road,,,
I was then feel very happy because maybe this discovery was the first since amateur lunar observing history.
I have made this artistic conception today, a Lunar horizon landscape viewed from on one of the the three [Tuna-fish like hills] which located on the bottom of 4 km wide, 80 km long magnificent rill.
I dont know how many billions of years have passed on this geological creation,formation, or evollution forces- sequences.

hi asod,I send my last observation of the Crab Nebula.this day the sky seemed to be good, but later was completely clouded wind.with these bad conditions, I was pleased with the observation.greetings and thanks.

Hello Artists!
When I sketching, usually I use black paper and jelly pen.
How can I do the more realistic expression?
The open cluster is glittering in the black sky.
So I thought that I can express this glittered stars with the beads!
How is this work?
(Please watch by the large-sized display with most bright mode)

Title: Petavius crater
My name: Silvia Fabi
Object name: Petavius
Object type: moon’s crater
Location: Ferrara
Date: 13/04/2013
Media: HB pencil on white paper
Seeing: III (Antoniadi)
Description: this is my favourite crater! It has a diameter of 177 Km and it’s deep 3,4 Km. It is a very intresting crater because it has a lot of central peaks and near this impact crater there are many floor’s irregularities and shadows.
All observed with a Sky Watcher Dobson 254 mm, 200x magnifications.

Hello astro-sketchers, here my last contribution…
Object Name (Epsilon1/2 Lyrae the Double double)
Object Type (Multiple Star)
Location (Château de Berne – Provence – France)
Date (May 8th)
Media (watercolor and ink, inverted while scanning)
Epsilon Lyrae, the “double-double” star, seen in the 450mm Dobson of my friend Philippe.
During this 4th yearly animation made in the “Château de Berne”, a nice vineyard domain in Provence, I had the opportunity to sketch this difficult multiple star.
The northern star is called ε1 and the southern one is called ε2; they both lie around 160 light years from Earth and orbit each other. In this big 450mm eye, both stars of the binary can be further split into binaries; that is, the system contains two binary stars orbiting each other. The component stars of ε1 have magnitudes of 4.7 and 6.2 separated by 2.6″ and have an orbital period that can only be crudely estimated at 1200 years, which places them at roughly 140 AU apart. The component stars of ε2 have magnitudes 5.1 and 5.5 separated by 2.3″, orbit perhaps half that period. ε1 and ε2 themselves are not closer than 0.16 light years apart, and would take hundreds of thousands of years to complete an orbit.
I made the watercolor taking into account the further inversion needed, that means black for white and orange for blue, for example.
